GeForce GTX Titan Z EVGA Hydro Copper 12GB Edition is a special edition of the enthusiast GeForce GTX Titan Z. This edition comes with a custom cooling solution which by itself should allow a slight performance boost, as GeForce GTX Titan Z benefits from the GPU Boost 2.0 technology. Also, it has been overclocked out of the box from 705MHz to 758MHz while its boost clock is now of 941MHz. The memory clock was left untouched. Benchmarks indicate a 6% performance boost when compared to the reference card and so both GeForce GTX Titan Black in SLI and Radeon R9 295X2 are still faster.
